The tea cup hold is Hollywood endorsed as it allows the camera to get a better framing of the movie star with pistol in hand, rather than a proper hold and actually looking thru the sights which obscures the famous face in the scene. The screwed up hand grips are everywhere and its painful to view it where it shouldn't ever be present - why would a mfg. serrate the front of the trigger guard if it wasn't useful?...uninformed engineers or firearm consultants perhaps. Someone somewhere thought breaking up your support hand strength by wrapping the support index finger about the front of the trigger guard; that someone should be rounded and flogged for such teachings. 60% of your grip strength is in the index-middle finger grip; opening the grip to wrap the trigger guard weakens the support effort. Same reason the carabiner is weaker when the gate is open v. closed.
Got to love when the muzzle is helmet high when shooting a 9 mm!

Below: same deal, let's allow that muzzle to get ball cap high for that fast follow-up sight picture life saving shot.
